This release fixes the startup crash on Windows 10, shows the real Windows edition on the dashboard, and rewrites the French translation to read natively. Thank you to @gsyp10032 for the fix guidance [#86], to @Kevaee and @InsideMen0 for staying on the crash reports [#50], and to @Robocnop for the French rewrite [#89].

Fixes

  • The app starts on Windows 10 again. CET shadow stacks ship enabled in .NET 9+ hosts, but CoreCLR calls QueueUserAPC2 when shadow stacks are on, and that API only exists on Windows 11 / Server 2022. So every build died at launch on Windows 10 with 0x80131506 ("Unknown Hard Error"). CETCompat is now off, keeping the Windows 10 support the README promises. Thanks to @gsyp10032 [#86], @Kevaee and @InsideMen0 [#50].
  • The dashboard shows the real Windows edition. The Operating System card folded every Home-family SKU into Home, so CoreCountrySpecific (Home China) displayed as plain Home. It now reads the actual EditionID from the registry and keeps the family name next to it: CoreCountrySpecific (Home). IDs it has never seen display as-is instead of Unknown [#88].

Improvements

  • French rewritten to read natively. 819 strings reviewed, 232 rewritten. Literal calques rephrased, drifted recommendation reasons fixed, official Windows French terms used throughout. Thanks to @Robocnop [#89].
